“…Jest to pierwsze w naszym kraju stwierdzenie F. magna u zwierząt utrzymywanych fermowo oraz rejestracja nowego ogniska w południowo-wschodniej Polsce, w pobliżu granicy ze Słowacją. Badanie struktury genetycznej przywr pochodzących z tego ogniska fascioloidozy przy użyciu markerów mitochondrialnych wykazało genetyczną identyczność z haplotypami F. magna pochodzącymi z Republiki Czeskiej oraz z Borów Dolnośląskich w Polsce (13). Kolejne badania sekcyjne i molekularne zwierząt pochodzących z południowo--zachodniej Polski (z okolic Jawora i Nowogrodu Bobrzańskiego) wykazały inwazję F. magna u 13,6% saren, 70% jeleni i 33,3% danieli.…”

The aim of this study was to determine the prevalence of infection with F. magna flukes in roe deer from the conifer forest Bory Zielonogórskie. Parasitological dissection was performed on 20 roe deer hunted in May 2016. Faecal samples from the animals were examined by the decantation method. One roebuck was verified to be infected with F. magna, which yielded a prevalence of 5%. We noted fibrinous deposits on the diaphragmatic surface of the liver with adhesions to the diaphragm, as well as five dark-coloured nodular protrusions on the liver surface. In the cross section view of the infected liver, we saw five pseudocysts corresponding to the nodular protrusions observed on the liver surface. Three of the pseudocysts were filled with dark brown liquid containing a few flukes, their eggs and cell detritus. The other two pseudocysts contained dark fluid and fragments of dead flukes. Although, no liver fluke eggs were detected in the faeces, thousands of eggs were found in the pseudocysts. Previous studies in Poland revealed two foci of this parasitosis: in south-western and south-eastern parts of the country. It is possible that the range of both foci is expanding due to red deer migrations and the spread of infected water snails and larval forms of the parasite in watercourses and rivers. Fascioloides magna infection is a threat for cervids and domestic ruminants. Therefore, it is important to monitor the occurrence of this fluke in Poland. It is essential to determine the range of fascioloidosis, examine the intermediate host species and record cases of F. magna infection in domestic ruminants..

“…The migration of the C. elaphus between the two existing foci (southwest and southeast areas), the spread of the infected aquatic snails, and the larval forms of the parasite in the watercourses and rivers make F. magna infection a threat to cervids and domestic ruminants in Poland [ 50 , 51 , 52 ].…”

Fascioloidosis is a parasitic disease of primary wild and domestic ruminants, caused by giant liver fluke, Fascioloides magna. The definitive host of the liver fluke in its area of origin (North America) is the white-tailed deer (Odocoileus virginianus). In Europe, the red deer (Cervus elaphus) and European fallow deer (Dama dama) are definitive hosts and the most sensitive hosts to F. magna infection, on which the parasite exerts serious pathogenic effects. In this study, we analyzed fecal samples and livers of 72 D. dama from 11 hunting grounds in Arad County, Romania. Of the 72 fecal samples and livers from D. dama, trematodes of the genus Fascioloides were identified in four (5.56%). Sequencing revealed that the trematodes identified in the samples were similar to the sequence of F. magna (GenBank no. EF534992.1, DQ683545.1, KU232369.1). The sequence obtained from the molecular analysis has been deposited in GenBank® under accession number OQ689976.1. This study describes the first report of giant liver fluke (F. magna) infection in D. dama in Romania.

“…For a long time, the Czech focus was restricted only to the territory of Czech Republic (Ullrich, 1930;Leontovyč et al, 2014). However, the very recent fi ndings of F. magna confi rmed the parasite expansion into new areas in Poland, in particular Lower Silesian Wilderness (Pyziel et al, 2014; and Podkarpackie Province (Karamon et al, 2015;Juhásová et al, 2016). On the contrary, the Danube fl oodplain forests (DFF) represent dynamically expanding European natural focus of fascioloidosis even since the fi rst F. magna fi ndings in Austria (Pfeiffer, 1983), Slovakia (Rajský et al, 1994), and Hungary (Majoros & Sztojkov, 1994).…”

Transmission risk assessment of invasive fluke Fascioloides magna using GIS-modelling and multicriteria analysis methods

et al. 2017

SummaryThe combination of multicriteria analysis (MCA), particularly analytic hierarchy process (AHP) and geographic information system (GIS) were applied for transmission risk assessment of Fascioloides magna (Trematoda; Fasciolidae) in south-western Slovakia. Based on the details on F. magna life cycle, the following risk factors (RF) of parasite transmission were determined: intermediate (RF IH ) and fi nal hosts (RF FH ) (biological factors), annual precipitation (RF AP ), land use (RF LU ), fl ooded area (RF FA ), and annual mean air temperature (RF AT ) (environmental factors). Two types of risk analyses were modelled: (1) potential risk analysis was focused on the determination of the potential risk of parasite transmission into novel territories (data on F. magna occurrence were excluded); (2) actual risk analysis considered also the summary data on F. magna occurrence in the model region (risk factor parasite occurrence RF PO included in the analysis). The results of the potential risk analysis provided novel distribution pattern and revealed new geographical area as the potential risk zone of F. magna occurrence. Although the actual risk analysis revealed all four risk zones of F. magna transmission (acceptable, moderate, undesirable and unacceptable), its outputs were signifi cantly affected by the data on parasite occurrence what reduced the informative value of the actual transmission risk assessment.
